                               ------------------------

     ITT EDUCATIONAL SERVICES, INC., a corporation organized and existing
under the General Corporation Law of the State of Delaware (the
"Corporation"), hereby certifies as follows:

     1.   The name of the Corporation is ITT EDUCATIONAL SERVICES, INC.  The
Corporation was originally incorporated under the name Allied School of
Mechanical Trades, Inc., and the original Certificate of Incorporation of the
Corporation was filed with the Secretary of the State of Delaware on June 27,
1946.

     2.   This Restated Certificate of Incorporation integrates, amends and
restates the Certificate of Incorporation of the Corporation.

     3.   The text of the Certificate of Incorporation as heretofore amended
is hereby integrated, amended and restated to read in its entirety as follows:

     ARTICLE I:  The name of the Corporation is:

purpose are to engage in any lawful act or activity for which corporations
may be organized under the General Corporation Law of the State of Delaware.

     ARTICLE IV:

     SECTION 1.  The amount of total authorized capital stock of the
Corporation is 30,000,000 shares, of which 25,000,000 shares shall be Common
Stock, having a par value of $.01 per share ("Common Stock"), and 5,000,000
shares shall be Preferred Stock, having a par value $.01 per share
("Preferred Stock").



     SECTION 2.  Except for and subject to those rights expressly granted to
the holders of Preferred Stock, or any series thereof, by the Board of
Directors of the Corporation (the "Board of Directors"), pursuant to the
authority hereby vested in the Board of Directors or as provided by the laws
of the State of Delaware, the holders of the Corporation's Common Stock shall
have exclusively all rights of stockholders and shall possess exclusively all
voting power.  Each holder of Common Stock of the Corporation shall be
entitled, on each matter submitted for a vote to holders of Common Stock, to
one vote for each share of Common Stock standing in such holder's name on the
books of the Corporation.

     SECTION 3.  The Board of Directors is hereby expressly authorized, at
any time and from time to time by a resolution or resolutions, to divide the
shares of Preferred Stock into one or more series, to issue from time to time
in whole or in part the shares of Preferred Stock or the shares of any series
thereof, and to fix and determine in the resolution or resolutions providing
for the issue of shares of Preferred Stock of a particular series the voting
rights, if any, of the holders of shares of such series, the designations,
preferences and relative, participating, optional and other special rights of
such series, and the qualifications, limitations and restrictions thereof, to
the fullest extent now or hereafter permitted by the laws of the State of
Delaware.  The voting rights, if any, of each such series and the preferences
and relative, participating, optional and other special rights of each such
series, and the qualifications, limitations and restrictions thereof, if any,
may differ from those of any and all other series.  Unless otherwise provided
in the resolution or resolutions of the Board of Directors providing for the
issuance thereof, shares of any series of Preferred Stock that shall be
issued and thereafter acquired by the Corporation through purchase,
redemption, exchange, conversion or otherwise shall return to the status of
authorized but unissued Preferred Stock.

     Without limiting the generality of the foregoing authority of the Board
of Directors, the Board of Directors from time to time may (if otherwise
permitted under the General Corporation Law of the State of Delaware):

               (a)  designate a series of Preferred Stock, which may be
          distinguished by number, letter or title from other Preferred Stock
          of the Corporation;

               (b)  fix and thereafter increase or decrease (but not below the
          number of shares thereof then outstanding) the number of shares of
          Preferred Stock that shall constitute such series;

               (c)  provide for dividends on shares of Preferred Stock of such
          series and, if provisions are made for dividends, determine the
          dividend rate and the times at which holders of shares of Preferred
          Stock of such series shall be entitled to receive the dividends,
          whether the dividends shall be cumulative and, if so, from what date
          or dates, and the other conditions, if any, including rights of
          priority, if any, upon which the dividends shall be paid;

               (d)  determine the rights, if any, to which holders of the
          shares of Preferred Stock of such series shall be entitled in the
          event of any liquidation, dissolution or winding up of the
          Corporation; PROVIDED, HOWEVER, that in the event of any such
          liquidation, dissolution or winding up of the Corporation, the
          holders of the shares of Preferred Stock of such series shall not be
          entitled to be  paid out of the assets of the Corporation available
          for distribution to its shareholders, whether from capital, surplus
          or earnings, an amount in cash greater than $100.00 per share, plus
          accrued and unpaid dividends to the date fixed for liquidation,
          dissolution or winding up, whether or not declared.

                                     -2-



               (e)  provide for the redemption or purchase of shares of
          Preferred Stock of such series and, if provisions are made for
          redemption, determine the time or times and the price or prices at
          which the shares of Preferred Stock of such series shall be subject
          to redemption in whole or in part, and the other terms and
          conditions, if any, on which shares of Preferred Stock of such
          series may be redeemed or purchased;

               (f)  provide for a sinking fund or purchase fund for the
          redemption or purchase of shares of Preferred Stock of such series
          and, if any such fund is so provided for the benefit of such shares
          of Preferred Stock, the amount of such fund and the manner of its
          application;

               (g)  determine the extent of the voting rights, if any, of the
          shares of Preferred Stock of such series, including but not limited
          to the right of the holders of such shares to vote as a separate
          class acting alone or with the holders of one or more other series of
          Preferred Stock and the right to have more (or less) than one vote
          per share;

               (h)  provide for whether or not the shares of Preferred Stock of
          such series shall be convertible into, or exchangeable for, shares of
          any other class or classes of capital stock, or any series thereof,
          of the Corporation and, if so convertible or exchangeable, determine
          the conversion or exchange price or rate, the adjustments thereof
          and the other terms and conditions, if any, on which such shares of
          Preferred Stock shall be so convertible or exchangeable; and

               (i)  provide for any other preferences, any relative,
          participating, optional or other special rights, any qualifications,
          limitations or restrictions thereof, or any other terms or provisions
          of shares of Preferred Stock of such series as the Board of Directors
          may deem appropriate or desirable.

     SECTION 4.  Shares of Common Stock or Preferred Stock may be issued by
the Corporation from time to time for such consideration, having a value of
not less than the par value, if any, thereof, as is determined from time to
time by the Board of Directors.  Any and all shares issued and for which full
consideration has been paid or delivered shall be deemed fully paid stock and
the holder thereof shall not be liable for any further payment thereon.

     ARTICLE V:  The following provisions are inserted for the management of
the business and for the conduct of the affairs of the Corporation and for
the purpose of creating, defining, limiting and regulating the powers of the
Corporation and its Directors and stockholders:

     SECTION 1.  The business and affairs of the Corporation shall be managed
by and under the direction of the Board of Directors.

     SECTION 2.  (a)  The Board of Directors shall consist of not less than
three (3) nor more than 20 (twenty) directors.  The exact number of directors
shall be determined from time to time by a resolution or resolutions adopted
by the affirmative vote of a majority of the entire Board of Directors.

     (b)  The Board of Directors shall be divided into three classes, as
nearly equal in number as the then total number of directors constituting the
whole board permits, with the term of office of one class expiring each year.
At the next election of directors, directors of the first class shall be
elected to hold office for a term expiring at the next succeeding annual
meeting, directors of the second class shall be

                           -3-



elected to hold office for a term expiring at the second succeeding annual
meeting and the directors of the third class shall be elected to hold office
for a term expiring at the third succeeding annual meeting.  Subject to the
foregoing, at each annual meeting of stockholders the successors to the class
of directors whose term shall then expire shall be elected to hold office for
a term expiring at the third succeeding annual meeting and each director so
elected shall hold office until his successor is elected and qualified, or
until his earlier resignation or removal.

     (c)  If the number of directors is changed, any increase or decrease in
the number of directors shall be apportioned among the three classes so as to
make all classes as nearly equal in number as possible, and the Board of
Directors shall decide which class shall contain an unequal number of
directors.

     (d)  Notwithstanding the foregoing, whenever holders of any shares of
Preferred Stock, or any series thereof, shall be entitled, voting separately
as a class, to elect any directors, all directors so elected shall be
allocated, each time they are so elected, to the class whose term expires at
the next succeeding annual meeting of stockholders and the terms of all
directors so elected by such holders shall expire at the next succeeding
annual meeting of stockholders.  The number of directors that may be elected
by such holders of Preferred Stock shall be in addition to the number of
directors fixed pursuant to paragraph (a) of this Section 2.

     SECTION 3.  Subject to the rights of the holders of any shares of
Preferred Stock, or any series thereof, newly created directorships resulting
from an increase in the number of directors or any vacancies on the Board of
Directors resulting from death, resignation, disqualification, removal from
office, retirement or other cause shall be filled solely by the affirmative
vote of the remaining directors then in office, even though less than a
quorum, or by the sole remaining director, and each director so chosen shall
hold office for a term expiring at the annual meeting of stockholders at
which the term of the class to which he has been elected expires and until
such director's successor shall have been duly elected and qualified.  No
decrease in the authorized number of directors shall shorten the term of any
incumbent director.

     SECTION 4.  Any director may be removed from office with cause, by an
affirmative vote of the holders of a majority of the combined voting power of
the then outstanding shares of stock entitled to vote generally in the
election of directors, voting together as a single class.  Any director may
be removed from office with cause by the affirmative vote of a majority of
the members of the Board of Directors, other than the director who is subject
to a removal vote.

     SECTION 5.  Advance notice of stockholder nominations for the election
of directors and of business to be brought by stockholders before any meeting
of stockholders of the Corporation shall be given if required by, and in the
manner provided in, the By-laws.  At any annual meeting or special meeting of
stockholders of the Corporation, any such business shall be conducted as
shall have been brought before such meeting in the manner provided in the
By-laws.

     SECTION 6.  The Board of Directors shall have the express power, without a
vote of stockholders, to adopt any By-law not inconsistent with this Restated
Certificate of Incorporation or with any By-law adopted by vote of the
stockholders of the Corporation, and to amend, alter or repeal the By-laws of
the Corporation other than any By-law adopted by vote of the stockholders of the
Corporation, except to the extent that the By-laws or this Restated Certificate
of Incorporation otherwise provide.  The Board of Directors may exercise such
power upon the affirmative vote of a majority of the entire Board of Directors.
Stockholders may adopt any By-law, or amend, alter or repeal the By-laws of the
Corporation,

                                     -4-



upon the affirmative vote of the holders of shares having at least a majority
of the voting power of the then outstanding shares of capital stock of the
Corporation entitled (at all times and without regard to the occurrence of a
contingency) to vote generally on the election of Directors and other matters
submitted for stockholder approval, voting together as a single class.

     SECTION 7.  No director shall be liable to the Corporation or its
stockholders for monetary damages for breach of fiduciary duty as a director;
PROVIDED, HOWEVER, that to the extent required by the provisions of Section
102(b)(7) of the General Corporation Law of the State of Delaware or any
successor statute, as the same may be interpreted or amended from time to
time, or any other laws of the State of Delaware, nothing contained in this
Section 7 shall eliminate or limit the liability of a director (a) for any
breach of the director's duty of loyalty to the Corporation or its
stockholders, (b) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (c) under Section 174
of the General Corporation Law of the State of Delaware, (d) for any
transaction from which the director derived an improper personal benefit or
(e) for any act or omission occurring prior to the date when this provision
becomes effective.  If the General Corporation Law of the State of Delaware
hereafter is amended to authorize the further elimination or limitation of
the liability of directors, then the liability of a director of the
Corporation, in addition to the limitation provided herein, shall be limited
to the fullest extent permitted by such amendment.  Any amendment,
modification or repeal of this Section 7 shall be prospective only, and shall
not adversely affect any limitation of the liability of a director existing
at the time of such amendment, repeal or modification.

     ARTICLE VI:  (a) Each person who is or was or had agreed to become a
director or officer of the Corporation, and each person who is or was serving
or who had agreed to serve at the request of the Corporation as a director or
officer of another corporation, partnership, joint venture, trust, employee
benefit plan or other enterprise (including the heirs, executor,
administrators or estate of such person), shall be indemnified by the
Corporation, and (b) each person who is or was or who had agreed to become an
employee or agent of the Corporation or who is or was serving or who had
agreed to serve at the request of the Corporation as an employee or agent of
another corporation, partnership, joint venture, trust, employee benefit plan
or other enterprise (including the heirs, executor, administrators or estate
of such person) may be indemnified by the Corporation, in each case in
accordance with the By-laws, to the full extent permitted from time to time
by the General Corporation Law of the State of Delaware as the same exists or
may hereafter be amended (but, in the case of any such amendment, only to the
extent that such amendment permits the Corporation to provide broader
indemnification rights than said law permitted the Corporation to provide
prior to such amendment) or any other applicable laws as presently or
hereafter in effect.  Without limiting the generality or the effect of the
foregoing, the Corporation may enter into one or more agreements with any
person which provide for indemnification greater or different than that
provided in this Article VI.  Any amendment or repeal of this Article VI
shall not adversely affect any right or protection existing hereunder
immediately prior to such amendment or repeal.

     ARTICLE VII:  No action shall be taken by the stockholders of the
Corporation except at a annual or special meeting of stockholders.

     ARTICLE VIII:  The Corporation reserves the right to amend or repeal any
provision contained in this Restated Certificate of Incorporation in the
manner now or hereafter prescribed by the laws of the State of Delaware, and
all rights herein conferred upon stockholders or Directors are granted
subject to this reservation.

                                       -5-
